在Opera和Chrome中打印iframe内容 [英] Print iframe content in Opera and Chrome

问题描述

  contentWindow.focus（）; 
 contentWindow.print（）; 
  

此代码适用于IE，Firefox和Safari。但不要在Chrome和Opera中运行。这些浏览器打印整个页面。

我试图使用这个主题。但它并没有帮助我。

有人可以帮助我吗？

解决方案

这是Opera中的一个已知错误。除了以上解决方法的想法之外，您可能还想玩这样的东西：

  var clone = document.documentElement。 cloneNode（true）
 var win = window.open（'about：blank'）; 
 win.document.replaceChild（clone，win.document.documentElement）; 
 win.print（）; 
  

我没有测试过，但它应该在弹出窗口中创建页面的副本并将其打印出来，而无需再次从服务器加载内容或丢失可能需要打印的任何DOM修改。

I'm trying to print iframe content.

contentWindow.focus();
contentWindow.print();

This code works in IE, Firefox and Safari. But don't work in Chrome and Opera. These browsers print entire page.

I tried to use this topic How do I print an IFrame from javascript in Safari/Chrome. But it didn't help me.

Could someone help me?

解决方案

This is a known bug in Opera. In addition to the above ideas for workarounds, you may want to play with something like this:

    var clone=document.documentElement.cloneNode(true)
    var win=window.open('about:blank');
    win.document.replaceChild(clone, win.document.documentElement);
    win.print();

I have not tested this but it should create a copy of the page in a popup window and print it, without having to load the content a second time from the server or loosing any DOM modifications you may want printed.
